using namespace std;
int main()
{
char* pLocale = setlocale(LC_ALL, NULL);
std::cout << "setlocale(): " << pLocale << std::endl;
const std::regex r1("^(\\s+)?(.*?)(\\s+)?=(\\s+)?(.*?)(\\s+)?");
std::cout << "std::regex r1: OK" << std::endl;
setlocale(LC_ALL, "Ja_JP");
pLocale = setlocale(LC_ALL, NULL);
std::cout << "setlocale(): " << pLocale << std::endl;
const std::regex r2("asdf");
std::cout << "std::regex r2: OK" << std::endl;
// const std::regex r3("^(\\s+)?(.*?)(\\s+)?=(\\s+)?(.*?)(\\s+)?");
const std::regex r3("\\s+");
std::cout << "std::regex r3: OK" << std::endl;
return 0;
}
The output:
